Frequency F of a fire truck siren heard by stationary observer is F = (132, 400)/(331 +or- v) where +or- v is the velocity of the truck. Find the rate of change of F with respect to v when:

when the truck is approaching at teh velocity of 30m/s (use -v)
and when truck is moving away at a velocity of 30m/s (use +v)

Thank you!

There is a club. There are many people who are members of that club. On the entrance of the club there is a guard. He gives club members a number when they want to enter. The club member gives him another number back, related to the first. If the guard thinks that the answer is correct then he allows them to enter into the club, otherwise does not.

First, a man A comes to the guard. The guard gives him the number 12. The man A responds with 6. The guard allows him to enter.

Second, a man B comes to the guard. The guard gives him the number 6. The man B responds with 3. The guard allows him to enter.

Third, a man C comes to the guard. The guard gives him the number 8. The man C responds with 4. The guard does not allow him to enter.

Can you tell, what would've been the correct response?

Sir fermats last theorem states that there is no integer solution for x,
y and z in the equation x^(n)=z^(n)-y^(n) for n greater then 2

My statement is this that there are infinitely many solutions for z and y for a given x and n when x^(n)=z^(2)-y^(2).Please do not mix it with FLT or pythagoras theorem.The mathematical proof of this statement was very helpful for me in solving FLT on a single page by the formula of z^(n)-y^(n) along with the fact that there lies a common term between x,y and z when x+y=z that is n=1 in Sir fermats last theorem (not greater then 2)
